To put the record straight as someone always like to twist it to cause further annoyance, I didn't request Airnav send a unit out before mine went back, I asked for a swap, they kindly decided to send a unit out, that was not my request, I have thanked them for that in the forum and by email.
This post was just a public thanks but of course there is always someone who has to have their "2 cents worth" as well.
I stand by the comments I made, I am not going to discuss them on this forum as Airnav don't want me to, I am a Chartered Electronics Engineer and I know a lot about antenna systems, RF front ends and protection.
